控制轧制对高碳钢珠光体相变温度的影响

Effect of Control-Rolling on Pearlite Transformation Temperature of High Carbon Steels

采用压力-膨胀仪测定了高碳钢经控制轧制后,在连续冷却下珠光体的相变温度;并分析了不同控轧参数对珠光体相变温度影响的规律。实验结果表明:奥氏体形变使连续冷却下珠光体的相变温度提高。

Pearlite transformation temperature after control-rolling was measured by a pre-ssure-dilatometer for high-carbon steels under conditions of continuous cooling. The effects of control-rolling parameters on pearlite transformation temperature are discussed and a conclusion is drawn that the latter will raise during continuous cooling by virtue of control-rolling.
